居家安全暨門禁監控系統
為了解決JavaScript if return 的問題,作者林冠穎 這樣論述:
近年來,隨著科技的進步,居家安全已愈來愈受到重視,我們利用物聯網技術,嘗試提供一個安全暨舒適的居家環境。本論文中,主要是開發一個以樹莓派為基礎的居家安全暨門禁監控系統,此系統由門禁監控系統、環境監控系統兩大系統所組成。其中門禁監控系統使用元件包括樹莓派模組、RFID(Radio Frequency IDentification)、陽極鎖、磁簧開關模組、網路攝影機及無線網路傳輸模組。而環境監控系統使用元件包括氣體感測器、排風扇及無線網路傳輸模組。此系統之功能敘述如下:(I)使用者可利用RFID開啟門鎖,若為正確感應卡之卡號,否則應用網頁將照片寄送到使用者信箱,且門鎖不會被開啟。(II)當窗戶被
打開時會觸發磁簧開關模組,並將照片寄送到使用者信箱,且啟動警報器。(III)氣體感測器每秒回傳一次感測到的數值,若高於設定值則開啟排風扇,以利於空氣循環。本系統之基本功能已研製完成,可為住戶生活上提供一些安全性與便利性之選擇。
